We know when server run out of CPU capacity, and we want to
increase the priority of a process running on CPU, we can lower the nice
value of that process so it get more CPU power than other processes, so its
job get done quicker.
What about, say, 10 processes are competing for Disk IO
resources. And I want process pid=100 to get higher priority on competing
disk io resource with other processes. Does renice has that kind of
function, or some other command/utility can do that?
